T0 LZZ whom it may concern:

Beit known that I, ERNST ENDERES, a citizen of the United States, and a resident of Lit- 4 4 of Fig. 2.

My wrench is especially designed for purpose of applying and removing what are generally known as the never-slip horseshoecalks and comprises, as shown, a hooked javi7 A, a handle-bar B, having a jaw C to oppose the hooked jaw A, a rocker D, and a nut E. As shown, the jaw A has the hooked portion A', which is cupped in its upper side at A2 to it around the calk, and said jaw A is also provided with the shank A3, which is made non-circular and is preferably attened, as best shown in Fig. l, and at the end of said shank A3 is provided the threaded stem A4 to receive the nut E.

The rocker D is in the form of an open box, having the opening D formed through it to fit upon the upper end of the non-circular shank A3, and the lower surface D2 of this rocker is rounded, so that it rocks upon the upper surface B2 of the handle-bar B adjacent to thev jaw C, the surfaces D2 and B2 being curved, so that they will properly rock upon each other in the use of the invention. The nut E turns upon the threaded stem A4 downv against the rocker D and may be turned to secure the desired adjustment of the jaws A and C.

rlhe handle-bar B is provided immediately in rear of its jaw C with an opening B', in which operates the shank A3 of the jaw.

The opening B in the wrench-handle B is elongated in the direction of length of said handle and has its end walls sloped rearwardly and adapted to permit the proper operation of the handle in setting the jaws of the wrench into engagement with the part to be operated.

In operation when the jaws are fitted around the calk and the handle is moved in the direction of the arrow in Fig. 2 the jaws will grip the calk and hold it until the handle is pulled back in the reverse direction, when it will release the calk, so that the handle may be reciprocated to turn the calk in one direction or the other, the cupped hook operating to tightly grip the calk and preventany slipping of same in the use of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isl 1. The improvement in wrenches herein described comprising the hooked jaw having its hook cupped in its inner side and provided with the projecting non-circular shank and at the end thereof with a threaded stem, ithe v handle-bar having at one end a jaw to oppose the hooked jaw and provided adjacent to said jaw with an opening extending through the handle-bar approximately at a right angle to the direction of lengththereof and adapted for the passage of the non-circular shank of the hooked jaw and having its upper surface adjacent to said opening rounded forming a seat for the rocker, the rocker fitting over the upper end of the non-circular shank and having the rounded edge rocking upon and sliding along the rounded surface of the handle-bar whereby the jaw ofthe latter may follow the inner curve of the hooked jaw,` and the nut on the threaded stem and operating upon the rocker, substantially as' set forth.

2. A wrench for use in manipulating horseshoe-calks comprising the handle-bar having the end jaw and adjacent thereto an open-ing formed transversely through said handle-bar from front to rear and the hooked jaw having its inner or jaw face curved and grooved or recessed from its point and provided with a projecting shank fitted to the opening in the handle-bar and projecting beyond the same, the rocker on the shank and having a convex face rocking upon and sliding along the handle-bar and adapted to move ina denite relation to the curved inner surface of the hooked jaw, and the securing-nut, substantially as set forth.

3. The combination in a wrench for use in manipulating horseshoe-calks, of the handlebar having the end jaw whose edge or extremity is formed straight and approximately at a right angle to the direction of length of the handlebar and provided adjacent to said jaw with a transverse opening from front to y yrear and the hooked jaw havingV an inner curved jaw-face grooved or recessed longitudinally from its point and provided With a projecting shank fitting in the opening in the handle-bar and securing means, the square straight face of the handle-jaw being` arranged to move along the curved inner face of the hooked jaw, substantially as and for the purpose set forth.
